This is a really interesting concept that I'd never heard of before... I'm not sure if playing a healslut or someone forced into a culture like that who expected to be a normal healer would be more fun... Hmm.

By the way, I should note that the healslut fetish can be turned on its head in entertaining ways, as well. What do you think of the idea of a masochistic tank, someone who puts herself between her team and the enemy because she gets off on being a target of abuse? And then imagine a character like that having their leash held by a far more dominant healer, and how much fun that could be.

And then, of course, as I understand it, DPS characters are typically the low man on the social ladder in most MMOs, and often have trouble finding groups due to the role being the most common and requiring the least amount of skill. I could easily see some damage-based wizard or sorceress being so desperate to find a raid group to party up with that she'd be willing to do absolutely anything for the privilege of being granted a spot on the team. And once she's on it, of course she'd have to work extra-hard to keep her team satisfied with her in order to keep herself from being replaced...

There's all sorts of possibilities for dominance and submission in tabletop dungeon crawlers and MMOs, really. ^^
